Hi, You may have come across this. Ulteo is a Linux distribution that appears to draws on concepts of cloud computing.
There is an online (KDE) desktop available that has a set of standard Linux applications such as as openoffice and the likes. With 1GB storage space per account at their servers (free), it looks like a very interesting online desktop. Check it out: http://www.ulteo.com If you like it, why not post a comment on their forum, asking about adding LyX to their online desktop. Cheers, Sam http://distrowatch.com/table.php?distribution=ulteo
